Okay, I have used three other Tenga eggs so far with my boyfriend. Each of them has had a slightly different feeling but they all are basically the same material. The ridges form differently inside. This one isn't as pronounced as some of the others with its ridges but gives a pleasant feeling. We have learned not to pour too much lube in them. I literally poured like just a small nickel sized amount in there and then just squeeze it to rub the lube all over the inside. Just like with the other eggs, Tenga eggs provide a different feeling from other toys. I feel like the eggs are very easy and convenient to use for a quickie. I love to use it as foreplay with my boyfriend. I just slip it over his cock to get it hard and going for a few minutes and then use my mouth. The lube this comes with is really neutral and won't get in the way at all. In fact, I quite like it because I feel like it's a million times better than my own saliva. Point is, these eggs are awesome. They give you that perfect amount of starting build up to move onto the real thing, finish with it or move onto another toy like the Tenga cup. Try not to be rough and be responsible to clean up after using it. This toy is made for a single use but definitely can be used more times. Try an egg and you won't be disappointed!
